Laser welding is a new type of welding method. It is mainly aimed at welding thin-walled materials and precision parts.Spot welding, butt welding, stitch welding, sealed welding, etc. can be realized with a high aspect ratio, a short welding distance, and a small heat-affected environment.
Minimal deformation, rapid welding speed, smooth and beautiful welding seam, no need to manage or easy welding operation, high welding seam consistency, no air holes, precise control, small focus location, high positioning precision, easy to realize automation.
The application range of the laser welding system is growing wider and wider and has increasingly entered the different industries. And with market demand, laser welding machines steadily replace plasma welding machines. So, what's the difference between the laser welding machine and the plasma welding machine?
What are the similarities and differences between laser welding machine and plasma welding machine?
1. The similarities between laser welding and low temperature plasma arc welding.
Both the laser welding machine and the plasma welding machine are part of the general arc welding method; the heat temperature is high and the electrical welding system can weld high melting point raw materials; both can carry out electrical welding with small circular holes to sustain single-sided welding on both sides.
2. The difference between laser welding and low temperature plasma arc welding.
The medium-temperature plasma arc of the plasma welder is basically part of this reduced electrical shielding, while the laser is part of the photon flow with strong monochromaticity, accuracy and consistency; the high laser intensity is 106-129w/cm2, while the low temperature The plasma arc is normally 106w/cm2; The maximum temperature of the laser heater is much higher than that of the low-temperature plasma arc; the particle beam is very simple to concentrate, emit and direct and can be attached to CNC machines or intelligent robots, non-touch manufacturing and processing, compact Laser welding equipment is difficult and costs increase; the low-temperature plasma arc welding machine has simple structure and low cost.
3. Application of laser welding and low temperature plasma arc welding.
Laser welding is commonly used in industrial, rail, large-scale machinery, shipbuilding, aerospace, medical and other industries; low-temperature plasma arc welding is used in engineering and manufacturing; Copper and alloy copper and titanium are widely used in automotive and top-of-the-line industrial manufacturing processes and electrical welding of titanium sheet, carbon steel, stainless steel shell, molybdenum and other metal components such as Titanium cruise missile casing and thick-walled warships.
